“They are already producing a backstory movie just about Cyborg.”
I don’t think that will happen. Ray Fisher, the guy that played him, seems to be persona non grata with Warner Bros. now. He has done a lot of public bellyaching about how some of the creators treated him. Racism, ya know. WB investigated his complaints and concluded they was no substance to his complaints.
Then they should make a Cyborg movie and cast a white guy in the role. That would be awesome.
